What a GMC VIN tells you
Every GMC built since 1981 has a 17-character VIN. The first three characters (the World Manufacturer Identifier) show who built it and where; characters 4–8 describe the model, body and engine; the 10th character is the model year; the 11th is the assembly plant; and the last six are the vehicle’s serial number.
| VIN starts with | Usually means |
|---|---|
| 1GT | GMC trucks built in the United States |
| 1GK | GMC SUVs built in the United States |
| 3GT / 3GK | Built in Mexico |
Prefixes are a general guide. The decoder above reads the full VIN for the exact details.
How to get the original GMC window sticker
GM keeps sticker records for many recent Chevrolet, GMC, Buick and Cadillac vehicles, but availability varies by model year, so not every VIN will have an original sticker on file.
GMC Sierra and Denali
GMC trims like Elevation, AT4 and Denali come with very different equipment. The original window sticker, or the RPO codes on the glovebox label, confirm which one a truck really is.
Where to find the VIN on a GMC
- On the dashboard on the driver’s side; look through the bottom of the windshield
- On the label inside the driver’s door frame
- On the title, registration card and insurance card
